Hello there!
Sorry to hear that you faced such an issue.
The thing is that the time column isn’t displayed on mobile devices when the “Mobile Behavior” option is set to “List”. And the problem is that you don’t display event times on your timetable. So that’s why your website visitors don’t see any event times when they load your website on mobile devices. In this case, you can either enable the event times in your timetable or, as an option, keep the “Mobile Behavior” option on the “Table” value so the time column can be visible.?
Another way out would be to enable the event times in your timetable so they can be visible on mobile devices, and then apply a custom CSS code to hide them on desktops where the time column is visible, for example.
